The main objective of the Earthing is to create low impedance path to flow the excessive / Leakage Current into the ground. The Primary Purpose of the good Earthing / Grounding system is to reduce the risk against excessive / Leakage Current to human life, property, Plant & Machinary. Good Earthing provides protection against huge electrical current, like lightning strikes, power surges & hazardous static electrical charges. The fundamental fact of electricity is that it always flows to the point of lowest potential. Electrical earthing/grounding ensure that electricity including faults,lightning and electronic noise are flown to this point with maxim- -um safety to people and at the same time the reliability of equipment is also maintained. The basic object of the Lightning Protection System (LPS) to protection against a direct impact of a lightning stroke and an internal protection against transient voltages produced by lightning strokes in the proximity on conductors of the electrical / data & communication network.
